The summary of experience and effect observation of cochlear implants in adults with different causes / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#This article summarizes the matters warranting consideration in adult cochlear implants before and after operation with different deafness causes and investigates the impact of etiological variables that affect hearing and speech ability rehabilitation after cochlear implantation.@*METHOD@#We retrospectively reviewed the preoperative data of 30 adults who have received cochlear implantation, switch on, and periodical post operative mapping. 'Nijmegen Cochlear Implant Questionnaire' was used for every patient during follow-up and test their hearing thresholds at one year after switched-on. The average score of every patient in the six aspects of questionnaire, along with the average hearing threshold, has been gathered.@*RESULT@#The average hearing threshold of every patient is lower than 35 dBHL. The average score of 28 patients is more than or equal to 75 in the basic sound perception, advanced sound perception as well as self-esteem. The average score of 26 patients is more than or equal to 75 in capacity for action. Besides, as for sociability and speech ability, the average score of 22 patients is more than or equal to 75.@*CONCLUSION@#Auditory perception can be greatly improved regardless of deafness causes, on the premise that appropriate candidate is selected. The primary disease should be brought under control before and after the operation. The influence of various causes to the language ability rehabilitation largely depends on the development of the language center at deafness onset. Self-esteem and social identity can be significantly enhanced after cochlear implantation in adult patients, particularly those with acquired deafness.
